Hope this helps someone !

Have you noticed any significant increase in heat between 450 and 500+ ? ?

Are you using the standard heat sink fan combo? what's the board temp? Mr.Spoon

Tim. I am thinking of doing the 300A overclock upgrade. It looks like in your experience about 3 out of 4 work fine. Problem is my luck always will make me the unlucky 1 in 4. However I was wondering if you had any experience with the success rate of the retail boxed 300A?? I have read that they may have a better success ratio. I am debating wether to go with the retail boxed 300A or buy from Computer Nerd - they test and sell those 300A that have worked well at 450 for $240 on a Abit BH6 with a quality cpu coller fan. Thanks for any info! --- Steve

C300A bought it today and 504mhz is GOOD !!!! huge # of 300a chips,and out of the 45 I have put to the test not one would run at 504 with any kind of stabilty. There were at least 5 that would boot to 504 but were very unstable.On the other hand, 33 were flawless at 450. And yes, I use the abit bh6.Voltage was not the issue. Mr. Overspeed

this CeleRon 300A Database......week 40 Malaysia are nearly all capable to run 504Mhz Look here....http://scripts.cac.psu.edu/users/b/l/blc146/cele300a.cgi

I did a bit of research here.....http://scripts.cac.psu.edu/users/b/l/blc146/cele300a.cgi and found that nearly all Malaysia week 40 retail CeleRons are capable of running 4.5 x 112 . It's too much work to put all he CMOS settings on here...i basically read everything at http://www.bxboards.com.....excellent site. I did install an extra fan to blow at the CPU and that's the only change from my previous CeleRon non-L2 cache 448Mhz. Cheeers for now !

Buy a week 40 Malaysian retail CeleRon 300A ......that's what i looked for http://scripts.cac.psu.edu/users/b/l/blc146/cele300a.cgi Go to this kick-ass site and for best overclocking info http://www.bxboards.com

Hi, I have had good luck with a Retail version 300A OCed to 450 for about 2 months now no problems. I would reccomend the Retail because the fan & heat sink is well worth the 20 bucks extra. Also I added one more case fan plus the little one I have always had on my V2 card. ( of course the power supply fan blows out ) Also if you like this site.......... http://www.minotaur.com/ sells pretested to 450 Celerons for $168 ( retail boxed ) thats a good price as I paid 180 untested. You can always find the Abit BH6 board for $99 at most places. Good Luck have fun this is a great easy project with great rewards I think :-) Cya, Mike > Tim.

And I said "huh" stable with Mitsubishi 8ns ECC RAM on BH6 with boxed 300A.
